Patented Sept. 23, 1930 JOE a. JONES, or PERU, nniannsxa q rnorroonArrr-nnconn Aim-sum i Application filed December ztlljieaagsfeiiai iig aaaoif i I The present invention relates to a device for accurately locatingphrases upon disk phonograph records. This device is in the nature of an instrument which measures the 6 grooves of a disk phonograph record along the line which is the radius of the disk so that V the needle of the tone arm may be placed at any particular point on the record for playing a certain selected division thereof.

An important object of the invention resides in the provision of a device of this na- 'ture which is exceedingly simple in its construction, inexpensive to manufacture, strong and durable, accurate, easy to handle, and thoroughly eflicient and reliable in use.

With the above and numerous other ob jects in view as will appear. as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will i be hereinafter more fully described and claimed.

Figure 1- is a plan view of the device show- I ing the same on a disk phonograph record,

Figure 2 is a detail section on line 2-2 of Figure 1. V

Referring to the drawing in detail it will be seen that the numeral 5 denotes a flat- 30 wedge shaped sheet of celluloid, bakelite,

fiber composition or other suitable material I which is stiff, durable and may be scaled.

, The point end of the sheet 5 is denoted by the numeral Band is designed to form an are which is'fixed upon the spindle? ofthe phonograph record table and which has'a ball "bearing race with ball bearings therein as is indicated at 8 whose function is to facilitate the spindle turning with the device placed on top of the record. y The numeral 9 denotes a scale which may be marked oil" into millimeters but which may begraduated to fit the grooves of particular disk phonographrecords should a more accurate device be required.

This scale 9 is arranged. along one of the straight side edges as is apparent in the drawing. The outer margin is denoted by the numeral 10 and protrudes slightly over the edge of the record 11 thus facilitating the removal of the aevie after the correct place on i the record has been indicated.

1: Thismargininay' be decorated saitabiyir so desired; A The numeral 12 denot'esthe"v other ifid g infwlhiqhmaybe placed a suitable trade-mark or facts such as instructions or the like. 1 Under the device it is preferable to fasten a base of suitable soft felt or other similar I material which serves to protect the record l0 and clean the dust out of the groove. 7

This device is designed primarily for use in study of what is termed musical appreciation. By its use, any particular phrase of music may easily be located upon 'a given phonograph record without necessitating a search of the whole record by playing it over until the desired phrase is located.

Also it will aid in the study of certain examples of musical technique either vocal or fl instrumental which are to be found on phonograph records. The same applies to quotations on'records of speeches, plays,poems or the member 7 in the manner illustrated inc Figure 1 of the drawings. The needle is then placed at the desired point, this being determined through the mediumof the scale 9, after which the device is removed. During the placing of the needle the device is to beam held against rotation with the record by the hand of the operator.

This, therefore is a genuine time-saving device. It is thought that the construction, utility and advantages of the invention Wlllil now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invent-ion has been described in considerable detailmloo I merely for the purposesgof exemplification since in actual practice it attains the features v of advantage enumerated as desirable in the 7 statement of the invention and the above description.

It Will be apparent that changes in-the details ,of Construction, in the materials, in the size 'and proportions maybe resortedto WlthOllD departing from'the spirit or scope of the invention as hereinafter claimed or sacrificing any ofits advantages.

Having thus described n1y 1nvention',what I v I claim as new is: A device of the class described including a flat Wedge shaped sheet having a straight 'edgewith a scale therealong, the smaller end V of said sheet beingarcuate, and ball-bean iingsimounted insaid arcuate end to engage the spindle of a phonograph recordtable.
